Abstract :
Current polarimetric SAR speckle filtering algorithms emphasize speckle reduction, but their preservation of polarimetric information and the statistical properties between channels have never been examined. This paper analyzes the existing algorithms for their effectiveness in preserving polarimetric properties, and proposes an algorithm that is effective in both speckle filtering and the preservation of polarimetric properties
